3 Claims.

This invention relates to new, useful and important improvements in the art of modeling sculpture work, and it has for its object to provide means in the form of a compound, or com- 5 position of matter, whereby sculpture work in any and all of its variations may be performed With greater accuracy, in less time, and at a less expense than has hitherto been possible.

The compound, or material, which constitutes the subject matter of this invention, may be produced in any color, and will, when used or applied, quickly attain the hardness of a rock, or limestone.

Thus, while the said compound, when used, has the characteristics of limestone in appearance and durability, the finished product, or work, may, as said, be given any color, bright, metal, or otherwise, by adding to the compound the appropriate kind of dry (powder) color.

20 This new compound does away with any prearranged castings and plastering work, as the model may be built up and finished without any of the usual preliminary or intermediary steps.

In building up a model, layers of the compound hereinafter defined, may be applied in whatever thickness desired, preferably up to the thickness of one-fourth of an inch; said layers will form an integral binding with any former layer ap- 30 vious layer constitute a solid mass. The compound or layer has the form of a paste, sufficiently thick in itself to make it stand up or adhere to the surface to which it is applied. Thus a model may in this Way be built up directly and formed upon or with the basis of a skeleton frame or structure as a foundation, thereby producing any desired design, or piece of art work.

Another advantage of this invention, is to the effect that the color of the model, or piece of art 40 work, thus made, will be a true color, that is, the material used will be permeated with the color all the way through, so that no cleaning, or washing of the model, or art work, produced, will dim, reduce or eliminate the brilliancy of the color of the same, as is now commonly the case, where the colors are applied to the outer surface only of the model, or art work, for instance, by painting.

To the ingredients, hereinafter I named, and which constitute my devised compound, may be added castor oil, in the amount hereinafter stated, if it is desired, in order to slightly delay the hardening of the material or layer applied for the purpose to give more time for the artistic molding of the art work, or model.

It will thus appear evident that by the use of the devised compound many advantages are obtained, such as the elimination of preparatory or intermediate operations, the obtaining of true colors in regard to the art work, While the compound or material itself offers the greatest adplied, and will quickly together with said prevantages to the artist for doing minutely fine and precise modeling or sculpture work.

The said compound comprises the ingredients of sand, preferably fine sand, metal powder, talcum powder, and liquid solder, preferably as made by the firm of Le Page, Russia Cement 00., Gloucester, Mass, and consisting of waterproof lacquer, benzol, acetone, aluminum powder and camphor.

The compound is composed by mixing the fine sand, metal powder and talcum powder together, stirring the mixture well, and then adding to the latter liquid solder, which, in turn, is again stirred very well with the aforesaid mixed ingredients.

The compound will now constitute a finished product ready for use, and should preferably be stored in air-tight cans, and be used within a comparatively short period of time, for instance within about eight days.

It is advisable, when making the compound not to mix the liquid solder with the other ingredients before at the time, or a short time before the compound is actually to be used.

The said compound is preferably, mixed in the proportions, as stated below, although a good and useful result may well be obtained, if slight variations are made with respect to the proportions stated.

Per cent Fine sand 37 Metal powder 12 Talcum powder 12 Liquid solder 37 This compound will constitute a paste, which, when applied in layers, will quickly harden.

If it is desired, however, to delay the hardening of said material in order to give more time for the artistic workmanship, some castor oil, up to 10% of the amount of the liquid solder used, may be added to the aforesaid compound.

When the art work is thus finished, an abrasive, or agent, having the characteristics of a grindstone, may finally be applied to the surface of the model made from the compound or material hereinbefore described, by rubbing or grinding said surface of the model in order to provide said art work with a smooth and highly polished surface.

As, however, such polishing process will naturally slightly dull the brilliancy of the colors, the surface of the art work may finally have applied to it a very thin coating of acetone, in order again to bring out the brilliancy or high lights of the said colors. Said acetone may be applied to the surface of the art work by means of a very fine brush.

It is obvious, as hereinbefore stated, that slight changes may be made in the proportions of the ingredients and the making of the com- Per cent Fine sand 37 Metal powder 12 Talcum powder 12 Liquid solder 37 2. A compound, as. claimed in claim 1, and which has added to it an amount of castor oil.
